IPC: G01J5/12
Filed: 1957-02-06
Abstract: 834,134. Radiation measurements. GENERAL ELECTRIC CO. Ltd. Feb. 6, 1958 [Feb. 6, 1957], No. 4125/57. Class 40 (3). [Also in Group XXXVI] A radiation sensitive device suitable for measuring the temperature of a workpiece or a bath of molten metal comprises a thermocouple mounted in a cavity in good thermal contact with the good heat-conducting walls of the cavity, the cavity being closed apart from an aperture through which heat radiation is admitted. In the embodiment a number of thermocouples are mounted with their cold junctions on an annular nickel member, which is then stuck to the anodized resin coated surface of a slotted aluminium annulus. The nickel ring is then cut between each pair of thermocouple wires and leads attached to two adjacent sections of the annulus to form the thermopile arrangement shown in Fig. 3c. This assembly is clamped through the intermediary of mica washers between boss 9 of flanged member 12 (Fig. 1), and the cylindrical member 3, which are bolted together. The leads from the thermopile emerge from the cavity through an insulating strip 9 clamped between plate 5 and the cylindrical member. Heat radiation is directed on to the hot junctions by means of a quartz member 14 (Fig. 4), mounted in an integral glass envelope 15 which is clamped by threaded collar 17 to member 12. The quartz member is shaped to reduce loss of radiation through its side walls and at its inner end is a lens to concentrate the radiation on the hot junctions. The envelope, which may be dispensed with if the sides of the member are completely silvered, is silvered where it is joined to the member.

Title: Improvements in and relating to coin-freed mechanism for automatic vending machines
IPC: G07F5/04
Filed: 1929-02-14
Abstract: 329,644. Grraucob, F. Feb. 14, 1929. Coin action, mechanical-connection and multiple coin.-Relates to coin-freed releasing mechanism for the delivery drawers or slides of vending machines of the kind requiring two coins to effect the release, the coins being directed alternately to the till and to the release mechanism by a pivotally mounted divertor. According to the invention, the divertor g, Fig. 1, is of such a form and is arranged that, in the event of six coins being inserted without the withdrawal of the drawer slide, it will be maintained in a position to direct the seventh and succeeding coins to the till while leaving the release mechanism in a condition such that it may be operated to deliver goods. As shown applied to the release mechanism described in Specification 259,767, the divertor is pivoted immediately adjacent the release mechanism and its longer leg g<1> is curved to provide concave and convex portions h, i while the shorter leg g<2> consists of two outwardly curved parts h<1>, i<1>. The lever g is of a thickness equal to the thickness of two coins and the release mechanism can take two coins side bv side. If six coins are inserted without actuating the drawer, the first, third, and fifth go to the till, the second and fourth to the release mechanism. and the sixth is supported between those two latter coins and the portion i<1> as shown in Fig. 3, holding the divertor g to pass succeeding coins to the till. As each succeeding coin passes, the sixth coin is raised by the portion i<1>. When the drawer is actuated, the coins in the release mechanism and the sixth coin are discharged to the till. If the divertor and shoot f are of the thickness of one coin and the release mechanism takes a single coin only, the fourth coin inserted will be retained by the arm i<1> to hold the divertor in the position shown in Fig. 3.

Filed: 1972-02-03
Abstract: 1356875 Selective signalling ZELLWEGER Ltd 3 Feb 1972 [29 March 1971] 5036/72 Heading G4H Remote control is performed using n-bit commands, all having the same number of "ones", the commands being individual commands corresponding to particular receivers, and collective commands, receivers intended to respond to collective commands not testing some of the bit positions of the received commands, these bit positions including at least two of opposite binary value. The receivers responding to collective commands, can also respond to individual commands (those which are the same in the tested positions). The use of the same number of "ones" in individual commands as in collective commands, and taking the non-tested positions to be pairs of opposite binary value, reduces the ability of interference to produce incorrect control actions. In the receiver of Fig. 2, the bit values of the command are received at 24, preceded by a start pulse which starts a motor 26 controlling contacts 29, 30, 33 and stepping switch 40. Contact 30 switches on an SCR 50. A reversing switch 36 is positioned according to each successive bit value to apply pulses to lines S1, S2 and stepping switch 40 selects, in turn, bit positions in a command "key" 23. In the event of disagreement between a bit of the command received and the corresponding bit set up in the command "key" (assuming the latter bit is not set to neutral, as shown by dashed lines at 75, 74), the current is shunted through the command "key" away from SCR 50 which ceases to conduct. Finally, switch 33 is closed, and if SCR 50 is still conducting, an impulse switch 59 is actuated and the control function is performed (operation of a switch). Switch 59 reverses switch 77, 78, so that the next command to which the receiver is responsive is the bit-by-bit inverse of the previous one. A command and its inverse are respectively used for switching on and off the controlled switch. The command "key" may be a replaceable printed circuit, or reversing switches controlled by punched cards. In a first modification, the reversing switches 77, 78 are eliminated by duplicating the components 50-54, and using a bi-stable impulse switch 59 with two outputs. In another modification, the lowest fifth of Fig. 2 is common to a plurality of units each like the rest of Fig. 2, diodes being used for decoupling.
